[outflow gate valve]
Fig. 2 is the schematic diagram of the formation of the outflow gate valve 3 representing embodiment 1.
Flow out gate valve 3 comprise the screw actuator 21 producing electromagnetic attraction, the valve body 22 correspondingly worked with this electromagnetic attraction, the coil spring 23 exerted a force to valve opening position (in Fig. 2 top) by valve body 22 and to be connected with on pipeline 1 and to be than flowing out gate valve 3 by the pipeline 1a of master cylinder side and the valve body 24 of pipeline 1b dividing pump side.If valve body 22 below in Fig. 2 is mobile, then the top ends of valve body 22 is seated at the valve seat 26 being formed at valve body 24, makes pipeline 1a and pipeline 1b become valve closing state.On the other hand, if valve body 22 top in Fig. 2 is mobile, then the top ends of valve body 22 lifts off a seat 26, makes pipeline 1a and pipeline 1b become valve opening state.That is, the connected state (pressure reduction) of pipeline 1a and pipeline 1b is correspondingly determined with the above-below direction position (playing valve amount) of valve body 22.
Fig. 3 is the main portion enlarged drawing of the outflow gate valve 3 of embodiment 1.
Valve body 22 to be applied in Fig. 3 the outflow gate valve 3 of top power Fa pressure reduction corresponding to of the pressure (being equivalent to master cylinder hydraulic pressure) of upstream side with the pressure (being equivalent to wheel cylinder hydraulic pressure) in downstream, in Fig. 3 the power Fb corresponding to electromagnetic attraction of the screw actuator 21 of below and the application force of the coil spring 23 of top brings in Fig. 3 power Fc.By controlling the electric current passed into screw actuator 21, above-mentioned pressure reduction can be controlled to desired value.That is, the application force of coil spring 23 is correspondingly uniquely determined with the position of valve body 22.Therefore, if current value is controlled to specified value, then valve body 22 is advanced, and flows through to flow out the flow of gate valve 3 and adjusted, until the application force of electromagnetic attraction corresponding to this current value and coil spring 23 finally balances masterpiece that such above-mentioned pressure reduction brings mutually for valve body 22.Thus, the pressure reduction as target can be realized.Below, the balance called it as flowing out gate valve 3 controls.Such as, when screw actuator transfer valve 6 for open and screw actuator delivery valve 15 for closing, the supercharging amount of the wheel cylinder hydraulic pressure that pump P brings be according to the discharge liquid measure of pump P with determine from flowing out the difference of gate valve 3 to the leakage liquid measure of master cylinder M/C.When master cylinder hydraulic pressure is zero, the pressure reduction flowing out the upstream and downstream of gate valve 3 is equivalent to wheel cylinder hydraulic pressure.Therefore, as long as control the rotating speed (pump discharge liquid measure) of motor M, and be energized to the screw actuator 21 flowing out gate valve 3 in the mode making above-mentioned pressure reduction reach desired value and control its electromagnetic force, just automatically can adjust the aperture (above-mentioned leakage liquid measure) flowing out gate valve 3, can at random adjust wheel cylinder hydraulic pressure.

Fig. 4 is the diagram of circuit of the flow process of the outflow gate valve balance control treatment representing embodiment 1, below, is described each step.
In step sl, the target hydraulic based on wheel cylinder W/C calculates target liquid measure.
In step s 2, calculate in order to the pump delivery needed for the satisfied target flow calculated in step sl.
In step s3, the target motor rotary speed obtaining the required pump delivery calculated in step s 2 is calculated.Now, in order to realize suppressing the operating lag of pump P, improve the controlling flowing out gate valve 3, also the discharge rate Q α of regulation can be added required pump delivery, calculating the target motor rotary speed obtaining required pump delivery+Q α.
In step s 4 which, obtain deduction motor rotary speed, calculate according to deduction motor rotary speed and infer pump delivery.
In step s 5, deduct the target liquid measure calculated in step sl from the deduction pump delivery calculated in step s 4 which, what calculate outflow gate valve 3 passes through flow (the leakage liquid measure to master cylinder M/C leaks).
In step s 6, calculate by flow and pressure reduction (sensor values of target hydraulic and master cylinder hydraulic pressure sensor 4) target current value flowing out gate valve 3 according to what calculate in step s 5.
In the step s 7, carry out to the target current value calculated in step s 6 periodically (off and on) add that the target current that current value carrys out correction target current value of adding of regulation adds process.Here, though add current value be set to can obtain causing because of pump surging flow out gate valve 3 path increment change conditions under, also the position of valve body 22 can be made reliably to return to the size of the attractive force of the screw actuator 21 of control position (target location).In addition, the tap-off cycle that the cycle adding current value is set to pump P, the cycle (peak value of such as pump delivery) namely conformed to the swing circle of motor M is added.
In step s 8, target current value is put on screw actuator 21.
Next, effect is described.
